1 Claim. 1

The present invention relates to new and useful improvements in ladderplatforms or attachments and has for its primary object to provide, in amanner as hereinafter set forth, a device of this character which may beremovably but firmly mounted at substantially any desired point on aconventional straight ladder.

Another very important object of the invention is to provide a platformof the aforementioned character which may be readily adjusted to extendhorizontally from the ladder regardless of the angle of said ladder.

Other objects of the invention are to provide a ladder platform of thecharacter described which will be comparatively simple in construction,strong, durable, reliable and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawing whereinlike characters of reference designate corresponding parts throughoutthe several views, and wherein:

Figure 1 is a perspective view, showing a platform constructed inaccordance with the present invention mounted on a ladder.

Figure 2 is a vertical sectional view, taken substantially on the line22 of Figure 1.

Figure 3 is a fragmentary view in vertical section through a portion ofthe attaching means.

Figure 4 is a detail view in perspective of one of the connectingelements.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises aplatform 6, of suitable shape, dimensions and material. Fixed on theinner portion of the platform 6 is a pair of angular hooks l which areengageable over any of the rungs 8 of the ladder 9 for supporting saidinner end of said platform on said ladder.

Mounted on the outer end of the platform 6 is a metallic bar It whichterminates in upwardly bent end portions constituting standards I ArmsI2 in the form of metallic bars are pivotally connected at I3 to thestandards I I. At their free ends the arms I2 terminate in heads I d.The arms I2 have formed in their upper edges diagonally extending,longitudinally spaced notches I5.

A metallic coupling unit It adjustably and removably connects the arms I2 to the next highest rung 8 of the ladder 9. The unit I2 includes atransverse metallic bar I? having formed integrally therewith, atintermediate points, rung engaging hooks I8. Links I9 in the form ofmetallic straps are pivotally connected at an intermediate point, as at26, to the end portions of the bar IT. The links I9 include one endportion 2| which extends at an angle of approximately 45 and which hasformed therein a lonsol-31.5)

gitudinal slot 22 which slidably accommodates the adjacent arm if. Thelinks It further include right angularly bent inner end portions 23which are bifurcated and which slidably straddle the arms I2.

It is thought that the manner in which the device is used will bereadily apparent from a consideration of the foregoing. Briefly, thehooks 7 are engaged over the desired rung 8 of the ladder 9 and thehooks I8 are engaged over the superjacent rung of said ladder. To adjustthe pfatform 6 to a horizontal position regardless of the inclination orangle of the ladder 9, the suspension arms H are slid longitudinallythrough the links I9. The end portions 2| of the links I9 are engageableselectively in the notches It for positively securing the desiredadjustment. Of course, to remove the device it is only necessary to liftthe hooks l and I8 out of engagement with the ladder rungs. Theconstruction and arrangement, it will be observed, is such that thedevice may be expeditiously mounted for use on a conventional ladderwithout the necessity of making structural alterations therein.

It is believed that the many advantages of a ladder platform constructedin accordance with the present invention will be readily understood andalthough a preferred embodiment of the device is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction and in the combination and arrangement of parts may beresorted to which will fall within the scope of the invention asclaimed.

Having described the invention, what is claimed as new is:

A ladder attachment of the character described comprising a platform,means for attaching the inner end of said platform to a ladder, andmeans for attaching the outer end of the platform to said ladder, thesecond named means including a transverse bar mounted on a rung of theladder, links pivotally mounted on the end portions of said bar, saidlinks each including an angularly extending end portion having alongitudinal slot therein, arms pivotally mounted on said outer end ofthe platform and extending slidably through the slots, and heads on thefree ends of the arms, said arms having longitudinally spaced notchestherein, said angularly extending end portions of the links beingengageable selectively in the notches for adjustably connecting saidlinks to said arms, said links further including bifurcated angularlyextending end portions slidably straddling the arms.
